I had the name Sin 34 for a punk rock band in my head at age 15 in 1979. I even created a logo for it centered around a crucifix with S on the left side of the top center of the cross, the center being the "I" and N on the right, same with the 3 and 4 on the bottom of cross. It sounded real cryptic, but in actuality it was just a UHF television station based in Los Angeles (Spanish International Network -channel- 34).
